Application filed September 27, 1912, Serial No. 722,731. Renewed January 29, 1914; Serial No. 815,285.

To all whom it may concern.

Be it known that I, HENRY EMIL STREE- Bio, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented a new and useful Self-Adjustable Marginal Furniture for Printers, of which the following is a specification.

The present invention relates to improvements in extension furniture for printers, the present invention being the provision of an extension or adjustable furniture that displaces a large number and variety of stationary furniture in properly placing and securing type within the chase, the present furniture being composed of two similar members that are held together by a peculiarly formed interlocking joint which prevents accidental longitudinal and transverse movements thereof, but which permits the same to be readily collapsed or extended to accommodate itself to the desired location within the chase, the members being disposed to bemoved transversely upon each other or longitudinally with relation to each other, such longitudinal movement being independent of the transverse movement.

A further object of the present invention is the provision of a furniture of this char acter, provided with frictional means for retaining the twin members together against accidental extension or collapse, and yet permitting the same to be collapsed or extended longitudinally in a path wholly within the transverse contour of the members, thus per mitting the ready adjustment of the same when placed within a chase and in type holding positions and also retaining the members interlocked when not in use.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a perspective view of four pages of type matter locked up in the upper left hand quarter of a chase for press with the present invention in operable relation to the type therein, the said view showing a quarter of a sixteen page form, ready to print at one operation. Fig. 2 is a perspective view of the wider form of extension furniture. Fig. 3 is a cross section taken through the same to illustrate the position of the tongue and groove connections between the two members.

Referring to the drawings, and more particularly to Figs. 2 and 3, the extension furniture is composed of two similar members 1 and 2, each one of which is provided with the longitudinally disposed parallel-walled groove 3, in one side thereof, the same being provided with the oppositely disposed shouldered portions 4: terminating in the reduced parallel-walled slot 5. Extending from the inner end of each member 1 or 2 and upon the opposite side of its groove, is a tongue 6, which as shown is provided with the reduced or thinned web 7, extending the full length of the tongue and upon the inner face thereof, so that the web 7 may fit within the slot 5 with the shouldered portion of the tongue in frictional contact with the shoulders l, the outer face of the tongue being flush with the outer face of the coacting member and completely filling the groove 3 when the members are collapsed. These respective tongues and grooves are so fitted as to snugly engage and prevent the accidental collapse or extension of the members and at the same time prevent any lateral movement, the points of contact a between the tongues when the members are extended forming a friction means as well as the points of contact 6, c and (Z as illustrated in Fig. 3.

In placing the form in the chase, as clearly shown in Fig. 1, the page type T are separated and divided one from another by means of the self-adjustable marginal furniture, as illustrated, the form being looked as usual by means of the quoins W. It will thus be seen that with this form of furniture, that the web 7 is frictionally bound in the groove so that both members may be handled as one piece, such members being movable transversely upon each other, the bases of the web and slot being plane, to permit the members to be moved longitudinally upon each other, independently of their transverse movement.

What is claimed is:

1. An article of printers furniture com prising two counter-part members, each member being provided with a main portion and a tongue, the main portion being provided with a T-shaped longitudinally disposed slot that defines two longitudinal shoulders to cooperate ni'ith "the tongue of the other member and limit the insertion of the tongue transversely and 'to permit the-- tongue being frictionally bound to permit of the handling of both members as .a single part. I

2. An article of printers furniture comprising a pair of members, "each of which is providedin one longitudinal edge with a parallel-Walled groove terminating in a reduced, parallel-Walled slot, and is provided vadjacent its opposite edge and at its end with a projecting tongue having a thinned, inwardly projecting web, the tongue and the "web drone-member being mounted re spe'ctively, in the groove and the slot of the other member, and the 'web being frictionally boundin the groove whereby both members may be handled as one'piece, the mem- V hers being movable transversely upon each other, and the base of the Web'and the-slot being plane, to permit. the members. togbe moved longitudinally upon each other, independently of their transverse movement. In" testimony that I claim the foregoing as my town, I have hereto affixed my signa ture in the presence of two Witnesses.
